We ended up having to cut our vacation short due to Hurricane Matthew but I wanted to let everyone know how SDFP worked for my family of 6. I posted earlier about our success at MK. Overall everything worked great. We had our magic bands, 6 "used" cards and then 6, this year,
MNSSHP tickets to utilize. That meant I had 18 different profiles on my
MDE, which ended up being a challenge at times. If I had to do it over again I would have created a second MDE and kept the SDFP profiles on one and my primary profiles on another. Then I would utilize the MDE app to manage the primary and open the MDE on a search engine on my phone to be able to view the phantoms. I kept the cards separated by different colored rubber bands and would pass out the appropriate card depending on what FP we were using and this worked really well for us.
Having 18 names on my MDE became a bit of a challenge when I switched my MNSSHP from Thursday to Tuesday (glad I listened to my wife). They didn't question the amount of names but it definitely slowed the process of getting the party night changed. It also created a similar challenge when I asked for 3 day tickets to replace the days we were going to miss due to Hurricane Matthew. Again no issue was raised but it did take longer for the CM to add the comp tickets to the appropriate profiles.
SDFP were a challenge to obtain Tier 1 at Epcot and really proved not as beneficial since most of the Tier 2 were walk on. We were there on Sunday the 2nd of Oct. We ended up showing up late on Wed. to HS since we attended MNSSHP the night prior and were still able to obtain RnR as well as TSMM at about 11:00 am when we finally arrived. AK we were able to obtain additional EE and Safari FP but if you are going to be at the park late in the afternoon both were 15 min. or less waits in standby. MK, with the amount of FP rides, is where you will really benefit from SDFP's. 7DMT was not available but everything else was at around 10:00 am and I always searched for a party of 6.
I did check periodically throughout the day for FEA and 7DMT FP's and was only able to obtain one FEA on our Epcot day. We let our youngest daughter ride alone and she loved it. So I would encourage you to obtain those at the 60 day window if you are able.
With the weather impacting the majority of our trip, SDFP's really helped us maximize our touring plans and we ended up having a great time even though it was cut short.
